CLOTH-CUTTING MACHINE.

Specification of Letters Patent.

Patented o uly 4, 1911.

Application filed November 7, 1910. Serial No. 591,101.

To all whom it may concern:

Be it known that I, MORITZ WOLFE, merchant, a subject of the Emperor ofGermany, residing at 3 Brauerstrasse, Potsdam, Kingdom of Prussia,Germany, have invented certain new and useful Improvements in Cloth-Cutting Machines, of which the following is a specification.

The present invention relates to a cloth cutting machine, the cutter ofwhich passes from below through a table and reciprocates in a verticaldirection between a bifurcated cloth holder or foot.

For the purpose of allowing of employing the table for other kinds ofwork, when the machine is not in use, the cloth holder can be drawn offand the cutter can be folded down into a slit in the table; in suchposition the cutter may be locked so that even if the driving gear isunintentionally actuated, the cutter will not emerge from the table. Thelocking gear is furthermore so arranged that by its adjustment thecuttlng edge of the cutter is simultaneously covered and it isimpossible for anyone to hurt 111111- self on the same, both while themachine is in use and while it is idle.

In the accompanying drawing the pres ent invention is exemplified in aconstructional form, Figure 1 being a front elevation of the clothcutting machine, Fig. 2 a front elevation of the driving gear for thecutter with the table in section, Fig. 3 is a side elevation of thesame, Fig. 4 is a side elevation of the same, the cutter being in foldeddown position, Fig. 5 is a plan of the same, and Fig. 6 is a perspectiveview of the cloth holder with guard.

The cutter 1 is pivoted to the pitman 2 by means of a pin 3. Into thetable is cut a slot 4, into which the cutter may be folded. The cutteris encircled by the bifurcated cloth holder 5, which is attached to ashank 6, so that the clo h holder can be secured in a bore in the tableby snnply inserting said shank, or removed by drawing the shank out ofthe hole. Spring 7 securely holds the cloth holder in any position.

To the cloth holder 5 is fitted a guard 8 which is reinforced in frontby means of guide strips 9. The cutter has behind its pivoting point anose 10. To the under side of the table guide bars 11 are fitted. Belowthe pivoting point of the cutter the pitman 2 has a horizontalperforation 12.

When the shank 6 of the cloth holder is inserted into the hole in thetable the shank will strike against the nose 10 and move the cutterautomatically into the vertical work ing position, in which it enters byitself into the guard. The shank 6 will hold the nose 10 in suchposition also while the cutter is work ing, so that the cutter cannotswing down or emerge from the guard.

After the work has been completed, the shank of the cloth holder isdrawn out from the hole in the table and pushed with its guide strips 9like a drawer into the guide bars 11 screwed to the underside of thetable (Fig. 4:). The shank will then enter into the hole 12 and willbehind this hole strike against the nose 10 so that the latter is forcedupward and the cutter will fold down and enter into the guard. Thepitman is locked at the same time and prevented from reciprocating. Andas in consequence of the nose 10 resting on the shank 6 the cuttercannot be swung out from the guard, it is entirely out of question, forthe cutter to appear above the surface of the table, even if the treadleof the machine should inadvertently be moved. The guard prevents anyonedamaging himself while the cutter is folded down.

The peculiar design of the cloth holder renders it unnecessary for oneto touch the cutter with the hand, and by the adjusting of the lockinggear or the adjustment of the cutter and the cloth holder the guard isautomatically brought into position and its use enforced. In consequencethereof the working of the cloth cutting machine is not only extremelysimple but also absolutely without any danger whatever.

I claim:

1. In a cloth cutting machine, the combination with a cutterreciprocating vertically through a slot in a table, of a bifurcatedcloth holder, the cloth holder being removably attached to the table,and a guard for the cutter forming a part of the cloth holder,substantially as described.

2. In a cloth cutting machine, the combination with a cutterreciprocating vertically through a slot in a table, of a bifurcatedcloth holder, a shank secured to the cloth holder and removably fittedinto the table, and a guard for the cutter fixed to the cloth holder,substantially as described.

8. In a cloth cutting machine, the combination of a cutter reciprocatingvertically through a slot in a table, a bifurcated cloth holder, a shanksecured to the cloth holder and removably fitted into the table, a guardfor the cutter fixed to the cloth holder, and the cutter being arrangedto fold into the slot of the table when the guard is removed,substantially as described.

' 4c. In a cloth cutting machine, the combination of a cutterreciprocating vertically through a slot in a table, a pitman, the cutterbeing pivotally connected to the pitman, a cloth holder r emovablyattached to the table, and means whereby the cloth holder when in placeretains the cutter in an op erative position, substantially asdescribed.

5. In a cloth cutting machine, the combination of a cutter reciprocatingvertically through a slot in a table, a pitman, the

cutter being pivotally connected to the pitman and carrying a nose, abifurcated cloth holder, and a shank secured to the cloth holder andfitting through the table for engaging said nose to retain the cutter inan I operative position, substantially as described. V

6. In a cloth cutting machine, the combination of a cutter reciprocatingvertically through a slot in a table, a pitman, the cutter beingpivotally connected to the pitman and carrying a nose, a bifurcatedcloth holder, a shank secured to the cloth holder and fitting throughthe table for engaging said nose to retain the cutter in an operativeposition, and means for locking the cutter in its folded position whenthe cloth holder is removed, substantially as described.

7. In a cloth cutting machine, the combination of a vertical cutteroperating through a slot in a table, a vertically reciprocating pitmanhaving a bifurcated end, the lower end of the cutter being pivotallyconnected to the bifurcated end of the pitman and leaving a spacebeneath same, the lower end of the cutter carrying a nose, a bifurcatedcloth holder, a guard for the cutter forming a part of the cloth holder,a shank secured to the cloth holder and fitting through the table forengaging said nose to retain the cutter in an operative position, andmeans for slidably attaching the guard to the under side of the tablewhereby said shank will enter the bifurcation of the pitman beneath theend of the cutter and hold same in locked position, substantially asdescribed.

In testimony whereof I hereto aflix my signature in the presence of twowitnesses.

MORITZ VVOLFF.
